attorney Patented Sept. 19, 1950 UNITED STATES PATENT OFFICE AUTOMOBILE COOLING SYSTEM Martin F. Viedt, Winner, Dak. Application August 13, 1948, Serial No. 43,979

This invention relates to improvements in coolwaterjackets and pumps of internal combustion engines.

An object of this invention is to direct the flow of coolant first to that portion of the engine block where the highest temperatures are formed and then to those parts of the engine where relatively lower temperatures are normally generated.

Another object of this invention is to provide an even temperature cooling system for eliminating more rapid heating and expansion of'those certain portions of an engine where the greatest heat is formed by combustion while other portions of the engine are still relatively cool and contracted as is the case when an internal combustion engine is first started.

Still another object of the invention is to provide an even temperature cooling system that would eliminate expansion of one portion of the engine and relative contraction of another portion in order to eliminate cracked valve seats, cylinder heads and other parts of conventional internal combustion engines which are subject to wide variations in temperature.

A further object is to provide a radiator that will trap sludge andsediment in such a manner that it may be easily flushed out or removed without the necessity of complete dismantling of radiators.

Another object of the invention is to provide a device for the purpose described, which is sturdy and durable in construction, reliable and efiicient in operation, and relatively simple and inexpensive to manufacture, assemble and utilize.

Other and still further objects and advantages of the invention will become apparent from the following detailed description of a preferred embodiment thereof.

In the drawings:

Figure 1 is a side elevation of a radiator and a portion of an engine block, certain parts of the former being broken away to reveal the radiator core of the present invention;

Figure 2 is a vertical sectional view taken through the centrifugal pump and along the line 2-2- of Figure 3, a portion of the discharge pipe of the pump being broken away; and

Figure 3 is a view-in-section taken along the line 33 of Figure 2.

Referring to Figure 1, the numeral l0, gen- 1 Claim. (01. 123 41.21

' Th upper parts of the engine are enclosed by the water jacket I6. An inlet hose connection [8 is provided on the upper side of the water jacket l6. l

A radiator 22 is provided at its lower end wit a settling or -sediment tank 24 and at its upper end with a reservoir tank 26, the two being interconnected by a plurality of radiator cores 28 vertically disposed in the conventional manner.

A coolant circulation hose 30 is coupled at one end to the said inlet hose connection. l8 while its other end is coupled to the'upper reservoir tank26 of the radiator 28.

On the forward wall 32 of the cylinder block I 4 a centrifugal rotary pump 34 is secured by,

any suitable means, such as the bolts 36 to the front wall of the crank case I2.

A circulating hose 42 is connected at one end to the'lower settling tank 24 at a point spaced upwardly from the bottom thereof and at the other end to the discharge coupling 40 of the rotary pump 34.

As best shown in Figure 3 the rotary pump is provided with an inlet port 4| at its center erally indicates a conventional engine provided first mentioned pulley wheel and around 'the crank shaft pulley Wheel 54 whereby th crank shaft pulley transmits rotary motion in one direction to the rotary pump for circulating the coolant upwardly through the radiator 22.

In operation, the radiators upper and lower tanks together with the radiator core and the engines water jacket are filled with the coolant. At times when the engine is in operation the circulating water will first enter the upper side of the water jacket.

It will then be circulated to the most remote parts of the water jacket and become admitted to the intake aperure 4| of the rotary pump, discharged out of the side thereof into the lower circulation hose and the lower tank of the radiator.

It will be seen with this mode of circulation of a coolant through a radiator and a water jacket. that sludge and other sediment which accumulates therein falls downwardly to and becomes trapped and deposited in the lower radi ator tank 24, or becomes held to the lower ends of the radiator cores by the pressure of water circulating upwardly through the radiator 22, whereby at times when the engine is shut off the sediment will immediately drop down into the sediment trap 24 at the lower end of the radiator.

This invention. has provided an automobile cooling system which will provide more even cooling and which will reduce the clogging of radiators and other parts of a cooling system.

From the foregoing description, it is thought to be obvious that an automobile cooling'system constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facilityv with which it may be.

assembled and operated, and it will also be obviformation of the several parts herein shown in 5 carrying out my invention in practice, except as \claimed.

I claim: In an automobile engine liquid cooling system 4 including a radiator, said radiator having a sediment chamber at the bottom thereof; a pump; and a water jacket disposed about portions of said engine, said jacket being in communication with said pump adjacent the bottom of said jacket: means interconnecting the outlet of said pump with said sediment chamber at a point spaced upwardly from the bottom thereof; and othermeans connecting the top of said radiator with'said cooling jacket.
